Based on phylogenetic comparisons using the ITS and β-tubulin gene regions, these species were shown to be distinct from known species. These differences were also supported by robust morphological characteristics. The names, &lt;em&gt;Phytophthora frigida&lt;/em&gt; sp. nov. and &lt;em&gt;Phytophthora alticola&lt;/em&gt; sp. nov. are thus provided for these taxa, which are phylogenetically closely related to species within the ITS clade 2 (&lt;em&gt;P. citricola&lt;/em&gt;, &lt;em&gt;P. tropicali&lt;/em&gt; and &lt;em&gt;P.multivesiculata&lt;/em&gt;) and 4 (&lt;em&gt;P. arecae&lt;/em&gt; and &lt;em&gt;P. megakarya&lt;/em&gt;), respectively. &lt;em&gt;Phytophthora frigida&lt;/em&gt; is heterothallic, and produces stellate to rosaceous growth patterns on growth medium, corraloid hyphae, sporangia with a variety of distorted shapes and has the ability to grow at low temperatures. &lt;em&gt;Phytophthora alticola&lt;/em&gt; is homothallic and has a slower growth rate in culture. Both &lt;em&gt;P. frigida&lt;/em&gt; and &lt;em&gt;P. alticola&lt;/em&gt; are pathogenic to &lt;em&gt;Eucalyptus dunnii&lt;/em&gt;. In pathogenicity tests, they were, however, less pathogenic than &lt;em&gt;P. cinnamomi&lt;/em&gt;, which is a well-known pathogen of Eucalyptus in South Africa.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">11</style></issue></record></records></xml>
